Best answer
Correct answer is (b) Very Small

For explanation: Fuel injection system is the heart of diesel engine. In an injection system very small quantity of fuel must be measured out, injected, atomized, and mixed with combustion air. The mixing problem becomes more difficult. The larger the cylinder and faster is the rotational speed. However, special combustion arrangements such as pre-combustion chambers, air cells etc, are necessary to ensure good mixture.
